Preheat the oven to 350ºF and line one or two baking sheets with silicone mats or parchment paper. (Or bake at 400ºF for a 25-minute cooking time.)
Prepare the Tofu: Using the largest holes on a box grater, grate the block of tofu and spread it evenly on one of the prepared baking sheets. Drizzle with oil (optional), then add the tamari, nutritional yeast, garlic powder, and chipotle powder. Toss until the tofu is evenly coated.
Bake for about 30 minutes, tossing it halfway through, until golden brown. about 30 minutes at 350ºF, tossing it halfway through, until golden brown and crispy.
Notes
Choose Firmness: Use super firm or extra firm tofu, as softer types won’t hold up well.Spread the grated tofu in a thin layer on the baking sheet for crispier tofu shreds.For a shorter cooking time: Bake at 400-425°F for a shorter time, stirring frequently to prevent burning. If you are not using oil, use a quality nonstick baking sheet or line the sheet with a silicone mat or parchment paper to prevent sticking.
